I have an older stand-alone DVD player that does not recognize or play burnt DVDs well. The loader in the player is a standard PC IDE type DVD-ROM. After doing some research, I have found out that this loader can be directly replaced with a more modern DVD-ROM drive to allow it to read all formats of burnt disks.
The only requirements for the drive is that it be region free (the firmware in the player controls the region) or capable of being modified to region free and that the drive does not require something called “authentication”. From the actual instructions:
[I]Not all computer IDE DVD-ROM drives are compatible with the player. Some drives require an “authentication” process once a disc is inserted before the drive will retrieve the data from encrypted sectors on a DVD-ROM. The player firmware does not perform this authentication process, so a drive requiring authentication will only send unencrypted sectors to the player, causing a “skipping” effect during playback (not all sectors on a DVD-ROM are encrypted, so some will play normally). In order to successfully replace the DVD-ROM drive in the player, you need to use a drive that does not require authentication.
You may do a simple test to verify a drive that does not require authentication. First, load a DVD-ROM disc into the drive and make sure you don’t have DVD playing software that automatically starts when the disc is inserted. Second, try to copy all the *.VOB files from the VIDEO_TS directory on the disc to your hard drive. If they all copy without an error, then your drive does not require authentication and could be used in the player. If you get an error (will very depending upon OS) then the drive requires authentication and would not work properly in the player.[/I].
I would like to try this modification with a Lite-on drive. I know Lite-on drives can easily be made region free. What I don’t know is if any or all of them require this authentication. So, what I would like to request from all you owners of Lite-on DVD-ROMs is that you try the above test on your drive and report whether it requires authentication or not.
TIA for your help.
